1 . The problem of global warming has caused a lot of people to try their best to protect the environment. Unluckily, there are still many people who think it is hard to go green. In fact, it is very easy to be green in our daily life.

You can make a great start by learning to recycle (回收利用). While this looks really simple, there are many people who still throw glass bottles into their common garbage. Almost all cities offer a recycling bin (垃圾箱) for these items. If you put them in the recycling bin instead of throwing them away, you will be on the path to save the earth.

One good thing to recycle is newspaper. But there are still some people who just put their newspaper in the garbage when they finish reading it. As we know, there are many other things we can do with an old newspaper. For example, we can use it to clean our windows.

Another thing that could help you to start to live green is to begin walking a bit more. Many people think nothing of getting in their car and driving one mile to get drinks at the local store. If you walk to the store, not only can it take less time, because you won’t have to try to find a parking place, but you will be saving money on gas and helping to protect the environment. If you wish to save even more on gas, take the opportunity to car pool (拼车) each time you can, which has become popular in many countries.

There really are many means by which people can start living green. They only have to make some changes in their lifestyle to improve our environment.

2 . More than two thirds of the world's polar bears will be wiped out by 2050，according to a shocking new study. By then，scientists say，global warming will have melted 42 percent of the Arctic sea ice. By 2100，only a very few of these important creatures will be left.
The report has been produced by the US Geological Survey. The scientists have publicized their findings in the hope of influencing US Interior Secretary Dirk Kempthorne，who has been asked to put polar bears on the US endangered species list.
Polar bears depend on floating sea ice as a platform for hunting seals，which are their main food. Without enough ice，polar bears would be forced to go onto the land，where they are poorly skilled hunters，and would be unlikely to adapt to the life on the land in time. Experts say few little bears would survive and the stress could make many females unable to get pregnant.
The team of American and Canadian scientists spent six months studying bears，on the ground，from spotter planes and in the lab，using computer models.
Some team members fear the result is even worse for the bears than what their report says. They say the Arctic is warming faster than anywhere in the world and much faster than their computer had been forecasting. Satellite observations have showed that the ice has decreased to an all－time low.
However，not everyone in the scientific community believes that global warming is happening on such an alarming scale. Another investigation has found that polar bears are still being hunted by wealthy “sportsmen” who want their skins and heads. At least ten international companies offer bear－hunting trips.

C．Polar bears are an endangered species as a result of bear－hunting.

D．People don't pay enough attention to the protection of endangered species.

3 . A rainforest is an area covered by tall trees with the total high rainfall spreading quite equally through the year and the temperature rarely dipping below 16 ℃. Rainforests have a great effect on the world environment because they can take in heat from the sun and adjust the climate. Without the forest cover, these areas would reflect more heat into the atmosphere, warming the rest of the world. Losing the rainforests may also influence wind and rainfall patterns, potentially causing certain natural disasters all over the world.

In the past hundred years, humans have begun destroying rainforests in search of three major resources(资源): land for crops, wood for paper and other products, land for raising farm animals. This action affects the environment as a whole. For example, a lot of carbon dioxide (二氧化碳) in the air comes from burning the rainforests. People obviously have a need for the resources we gain from cutting trees but we will suffer much more than we will benefit.

There are two main reasons for this. Firstly, when people cut down trees, generally they can only use the land for a year or two. Secondly, cutting large sections of rainforests may provide a good supply of wood right now, but in the long run it actually reduces the world’s wood supply.

Rainforests are often called the world’s drug store. More than 25% of the medicines we use today come from plants in rainforests. However, fewer than l% of rainforest plants have been examined for their medical value. It is extremely likely that our best chance to cure diseases lies somewhere in the world’s shrinking rainforests.

4 . Ecotourism

    1     It is a new term in today’s tourism industry. But in an age of growing environmental awareness, it is not too difficult for us to imagine and understand this new form of holiday.

Ecotourism, which is considered as a kind of responsible tourism, is typically defined as travel to places where special and unusual plants, animals and cultural heritages are the main attractions.     2     Therefore, programs concerning the protection of some natural and cultural spots also form a part of ecotourism.

Ecotourism is developing at great speed. According to a recent report by the World Tourism Organization, ecotourism in recent years has enjoyed an annual growth of about 5% worldwide.     3     They include bird watching, hiking, diving, photography and taking part in various kinds of local cultural events.

If you love communing with nature, conserving the environment or improving the lives of people then ecotourism is an excellent way to see new and exciting places.     4     However, it looks like some smaller towns and country areas may well become the new destinations for people to visit tomorrow because they are rich in ecological, cultural and historical resources.

Ecotourism has been gaining increasing recognition and popularity mainly for the relaxing, natural and vivid experience it offers to tourists. People are attracted to nature and long to be close to it. However, a conflict between nature and human beings is unavoidable.     5    

A．The definition of ecotourism is beyond words.

B．It takes ecology and culture into consideration.

C．You may not be very familiar with ‘‘ecotourism’’.

D．More than 80 activities have been listed for ecotourism.

E．People can have great fun enjoying nature through ecotourism.

F．Big cities are still the major places that attract tourists in our society today.

G．How to protect natural resources while taking advantage of them is of great importance.

5 . A green roof is a roof of a building that is covered with vegetation over a waterproof membrane (防水膜). It is a proper method of growing plants on the roof and does not refer to the mere green color of the roof. People benefit a lot from these green roofing systems, and they are gaining popularity day by day.
Human beings have occupied major areas of land and transformed them into huge buildings, which has severely affected the environment and the natural habitat of bird and insects. Green roofing compensates for that. It creates a natural habitat for creatures like bees, grasshoppers and other insects.
Modern roofs need a lot of energy to control the temperatures in winter and summer. However, green roofs reduce the amount of energy required for controlling temperatures, thus making them energy-efficient. As green roofing is highly energy-efficient, it can act as a encouragement for people who are interested in green roofing systems and their benefits. It will increase the market value of the building and fetch the owner a great share of profit.
As the vegetation requires a water supply, there is a inbuilt water preservation layer in the green roof system. This layer helps to keep the rainwater. It makes full use of the rainwater and prevents wastage. During heavy rains, the water runs off the flat roof. The green roof prevents this overflow by slowing down the volume of running water.
Green roofs can compensate for the lost greenery in urban areas and increase the artistic value of an area. Your building will look beautiful, coated with green vegetation. Green roofs can serve as local community garden and create a natural atmosphere, giving physical and psychological benefits like reducing stress levels in people and keeping them physically fit. Besides, people can start their own small-scale cultivation (栽培) and experience the pleasure
of gardening.

6 . Researchers from the Massachusetts Institute of Technology (MIT) have discovered a new way of gaining the sun’s energy. A team from MIT has created a new technique of using a kind of special windows with chemical dyes (化学染料). The dyes help catch the light from the sun and send it to a special place in the window and then change the light into energy. The scientists say this discovery could change buildings into energy plants. It could even one day mean that the windows in our houses could provide power for our homes. The scientists say their dyes can produce ten times more power than the traditional solar (太阳的) board used around the world today. They also say that this clean and new energy technology could be available (可用的) within the next three years.

The idea was first developed in the 1970s but was given up. Scientists then found that too much of the collected sunlight failed to reach the places on the edges of (在……边上) the windows. Then the MIT engineers thought out the idea of using colored dyes to stop the light from escaping. At the same time, their method only requires cells (电池) around the edges of the windows. MIT’s Professor Baldo explained, “This special glass would let through about 10 percent of the sun to light up the room, and the left would be caught and used to create electricity for other fields. It would look like smoked glass because of the dyes.” He says the new technology could help fight environment change.

1. We can learn from the text that the dyes ______.

A．could also be used to get energy from plants

B．produce more energy than the traditional board

C．catch more light from the sun in the daytime

D．keep the light in the windows for longer time

2. What is the main advantage of this new technique?

A．It can be used to heat the room in winter.

B．It can be used to make the room colorful.

C．It saves people a large amount of money.

D．It is clean and good for the environment.

3. What’s the purpose of the text?

A．To show the importance of protecting the environment.

B．To encourage people to fix this special window.

C．To explain how to use this special window.

D．To introduce a new energy technique.

7 . As the population of the planet increases, so does the number of homes, business, parking lots, schools, airports and roadways. All these structures use electricity and need to be lighted. Humans demand light. They want their homes more comfortable and they want their streets safe. The problem is that researchers are finding that all the light is having a negative effect on humans and wildlife as well.

Less than 10 years ago I drove to a thinly populated section of my own, lay down in the middle of the road and watched an attractive meteor shower(流星雨). If I did that today, I wouldn’t be able to see the meteor shower.

Nowadays scientists are finding light pollution can be almost as bad as carbon dioxide （二氧化碳）pollution. One of the saddest parts of light pollution is that most of it is unnecessary and most of the outdoor light that we use is wasted. One only needs to look at a row of street lights to see how much of the lights shines upwards and lights the sky: a total waste of electricity.

Additionally, the production of electricity creates pollution by releasing greenhouse gases. This affects the air we breathe and our quality of life.

Scientists are also studying the effects of light pollution on wildlife. Thousands of birds die each year when they crash into highly lighted buildings, as they become puzzled by the light. It has been long known that tiny baby sea turtles become lost and follow the light on the shore instead of heading towards the sea.

Fortunately, light pollution is one of the easiest sources of pollution that can be corrected without a negative effect. Following some guidelines and a little searching on Google can give you many ideas on how to reduce your contribution to light pollution.

1. According to the passage, the best way to deal with light pollution is to ______.

A．Reducing the output of lights

B．Educating people about light pollution

C．Avoiding the use of unnecessary lighting

D．Inventing environmentally-friendly lights

2. What can be inferred from the passage?

A．Astronauts can’t see clearly in space nowadays

B．Global warming results in light pollution in some way

C．We are almost at a loss how to deal with light pollution

D．Some animals use natural light to direct their movements.

3. What will probably be provided following the last paragraph?

A．Benefits of searching on Google

B．More bad effects of light pollution

C．Helpful tips for suffering the Internet

D．Ways to decrease light pollution

9 . Sound travels very well through water-much better, in fact, than it does through air. So it shouldn’t be surprising that many ocean animals make noise. They use sound to communicate and hunt. As biologist Brandon Southall says, “Their whole world is related to sound.”

Dolphins whistle, organizing hunts. Lovesick whales sing so loudly they can be heard hundreds of miles away. But these days they aren’t the only ones sounding off. They have more and more competition from human machines.

Every day, thousands of huge container ships sail across the world’s oceans. On top of the engine noise, the ships’ propeller (螺旋桨) make a loud noise all the time. All that can make it hard for ocean animals trying to listen out for friends, or dinner. Animals swimming nearby a ship can be deafened or even killed.

Underwater construction can also be dangerously loud. When construction machines called pile drivers were used during repairs to the San Francisco-Oakland Bay Bridge, dead fish appeared.

Geologist (地质学家) pound on the seafloor too, trying to find oil wells and map Earth’s surface. The results are useful lo science, but all that hammering probably gives ocean animal a headache.

As people realize how important sound is to ocean animals, they are looking for ways to reduce human noise. Ships could get quieter just by slowing down. Engineers are also trying to find quieter propeller ships.

Now some companies are using a simple invention called a bubble curtain, which makes sound waves passing through it lose energy and gel quieter. It seems to work - when bubble curtains were fixed on the San Francisco bridge project fish deaths dropped.

We still have a lot to learn about sound in the oceans, but together we can help keep the sea a quieter place.

1. Dolphins and whales are mentioned to show       .

A．sound travels very well through water

B．they are surprisingly noisy in the sea

C．the ocean is filled with sound

D．ocean noise is a big problem

2. What is happening to ocean animals these days?

A．Human noise is causing danger to their safety.

B．There is less food in the ocean for them.

C．They are being killed in large numbers.

D．They are losing their hearing.

3. During the first repair to the bridge, some fish       .

A．started to die	B．were attracted to it
C．got quiet underwater	D．suffered from headaches

4. Bubble curtains are used to       .

A．research on fishes underwater	B．build the San Francisco bridge
C．stop noisy machines working	D．reduce construction noise
